German Automotives Partner to Make Battery Charging More EfficientEngineering360 News Desk | June 26, 2015
The partners will use GaN and SiC power semiconductors to reduce losses during charging and associated noise from fans, and expect these will help accelerate the move to what they say will be climate-friendly mobility.
The researchers have been able to reduce electronic power component losses during charging by 30%. They say that means less waste heat and, as a result, more compact and quieter cooling units.
The project also aims to determine how GaN or SiC power semiconductors can be used reliably in charging devices, voltage regulators and inverters for auxiliary power units. Research results are expected to accelerate the transition to air-cooled and fan-less systems for future generations of electric vehicles.
The 12 project partners include AVL Software and Functions GmbH, BMW AG, Daimler AG, Fraunhofer Institute for Integrated Systems and Component Technology IISB, the University of Applied Sciences Ostwestfalen-Lippe, Infineon Technologies AG, Lenze Drives GmbH, Robert Bosch GmbH, RWTH Aachen University, Siemens AG, Leibniz University Hannover and Volkswagen AG.
